Write a C++ program to print left arrow alphabets pattern using for loop.
#include<iostream>
using namespace std;
int main()
{
int rows, i, j, alphabet;
cout << "Enter Left Arrow Pattern of Alphabets Rows = ";
cin >> rows;
cout << "The Left Arrow Alphabets Pattern\n";
alphabet = 65;
for (i = rows - 1; i >= 0; i--)
{
for (j = i; j >= 0; j--)
{
cout << char(alphabet + j) << " ";
}
cout << "\n";
}
for (i = 0; i < rows; i++)
{
for (j = i; j >= 0; j--)
{
cout << char(alphabet + j) << " ";
}
cout << "\n";
}
}
C++ program to print left arrow alphabets pattern using a while loop.
#include<iostream>
using namespace std;
int main()
{
int rows, i, j, alphabet;
cout << "Enter Left Arrow Pattern of Alphabets Rows = ";
cin >> rows;
cout << "The Left Arrow Alphabets Pattern\n";
alphabet = 65;
i = rows - 1;
while (i >= 0)
{
j = i;
while (j >= 0)
{
cout << char(alphabet + j) << " ";
j--;
}
cout << "\n";
i--;
}
i = 0;
while (i < rows)
{
j = i;
while (j >= 0)
{
cout << char(alphabet + j) << " ";
j--;
}
cout << "\n";
i++;
}
}
